But that's a good thing. If you had signed up with high hopes, expecting something else, and then the product disappointed you, then you might write a bad review/blog post etc. potentially turning away other users who might have liked the features[1].
So if the features don't appeal to you, it's good in the long run for the creator to not have you as a beta user.
[1] the counter argument is that any publicity is good publicity :)
